Title: Improvements in manufacture of gas from oil or tar (hydrocarbons) or for cracking oil or tar
IPC: C10G9/26
Filed: 1926-03-16
Abstract: 269,711. Wannebo, K. N. March 16. 1926. Oil gas.-In the manufacture of gas from oil or tar by cracking in a chamber containing heatretaining material, after heating up the apparatus by burning oil or gas, oil is sprayed into the chamber through nozzles 5 and air introduced through inlets 3, the oil being gasified by passage through a heated chamber B to its outlet 7<1> from which the vapours and gases pass to a tar pot and heat exchanger 9 in which the oil is preheated. The temperature is maintained by the introduction at an inlet 3 of air which is heated by the chequerwork and then burns the carbon or lampblack deposited in the upper part of the chamber A the combustion products, mainly carbon monoxide, passing with the oil vapour to the chamber B. The addition of steam from inlet 6 forms water-gas. The direction through the chambers A and B is periodically reversed steam being blown in to displace unconsumed air before the reversal takes place.

Abstract: 1464849 Balloon limiters with liquidimpregnatable inserts BARMAG BARMER MASCHINENFABRIK AG 21 Feb 1975 [21 Feb 1974] 7332/75 Heading DID A balloon limiter 1 comprises an external housing 22, Fig. 3, releasably fixed in a liquid tight manner to the housing 22, the housing containing a liquid-impregnatable insert 7, 8, 9; the housing and the balloon limiter having openings 10 whereby liquid released by the insert 7, 8, 9 enters the balloon limiter 1. The insert 9 preferably projects through the openings 10 into the interior of the balloon limiter and the insert 7 can act as a wick drawing moisture from a further wick 17. In Fig. 3, a spring 31 biasses a housing 24 containing the liquid-impregnated insert 7, 8, 9 downwardly such that co-operating wedge-shaped surfaces force the insert 7, 8, 9 towards the balloon limiter 1. To change the insert 7, 8, 9 the screw 30 is released, the clamping wedge 27 is removed and then the insert 7, 8, 9 and housing 24 is removed. Replacement inserts may then be substituted. Fig. 4 (not shown) illustrates a modified embodiment in which leaf springs (37) biass the liquid-impregnated insert against the wall of the balloon limiter (8, 9, 38) such that the insert 9 projects through openings 10 into the interior of the balloon limiter. Figs. 1 and 2 (not shown) illustrate a further embodiment in which a vertically extending hand operated rod (11) carries eccentric cams (12), the rod and cams being so arranged that on a rotation thereof pressure is exerted on the liquid-impregnated insert to press it against the openings 10 in the wall of the balloon limiter.

Title: Feeding device for sewing machine
IPC: D05B27/18
Filed: 1948-03-10
Abstract: 634,031. Sewing-machines. FAIRWEATHER, W. C. (Singer Manufacturing Co.). March 10, 1948, No. 7333. [Class 112] Overhead sewing-machines. In a machine of the scale-pan type, for operating on flimsy and elastic material such as fine nylon, a device is provided for exerting a pull on the work substantially on the line of stitches to avoid puckering due to clinging of the stitches to the stitch-finger. In the embodiment shown, a resilient finger 26 fixed to the bearing sleeve 14 of the outer feed-cup 12 has its end twisted so as to be inclined transversely and arranged to bear on the outer edge of the rim of the feed-cup 12 so as to press the upper edge of the work on to this rim to be fed by it. The work is guided to the finger by the presser-member 24 described in Specification 547,644. The edge of the feed-cup rim is buffed to a slight radius to avoid damage to the work. Instead of having the usual serrated periphery, the outer feed-cup may have a resilient ring, for example of neoprene, bonded to it to provide the feeding surface. Specification 535,143 also is referred to.

Title: Improvements in metalclad withdrawable electric switchgear
IPC: H02B1/00
Filed: 1943-05-10
Abstract: 563,830. Switchgear structures. SWITCHGEAR & COWANS, Ltd., and UPTON, A. May 10, 1943, Nos. 7390 and 11110. [Class 38 (v)] In a withdrawable switchgear arrangement wherein a circuit-breaker when in operative position connects bus-bars m to an external circuit 12, the sockets j of the bus-bars, and if desired also, the feeder sockets 2, are connected over a switch n (and 13) to the bus-bars (and feeder), and withdrawal of the movable unit is prevented unless the bus-bars (and feeder) are isolated from their sockets and the latter are also preferably earthed. The operating handles 6, 14 of switches n, 13 are disconnectibly linked together at 15 and operate a sliding locking- plate d, but only when the breaker-handle g is in the " off " position. In the lowered position of plate d, a stop c thereon moves clear of knob b on the movable unit, so enabling the latter to be withdrawn, whereupon a stop z on the movable unit moves away from a spring-bolt y which moves so that a part x thereon overlays a knob w on plate d to prevent the latter's being restored. Also, in the lowered position of d and before the unit is withdrawn, the handle g cannot be closed, but the stop e allows the breaker handle f to be closed to earth the cable, provided handle 14 is uncoupled from handle 6 and moved to operative position. Earthing is effected at switch n, comprising, Fig. 5, a movable sleeve r adapted to connect a ring p either to the bus-bar contacts u or to the earthed frame v, the ring p being also connected to sockets j. With this arrangement the two sockets j, 2 may either both be earthed before withdrawal of the movable unit or, if switch 13 is not employed, Figs. 1, 2 (not shown), the bus-bar sockets are earthed and the feeder sockets can be earthed through the breaker when in operative position. The switch 6 may also interrupt auxiliary connections between the two parts of the gear, for example, voltage-transformer connections, Fig. 6 (not shown). A padlock 17 normally prevents unauthorized removal of coupling means 15, Fig. 10 (not shown).

Abstract: 181,449. Orendorff, O. H. March 8, 1921. Catches, automatic; catches yielding to pull or pressure; striking-plates.-A spring catch-device applicable for holding doors open or closed or for securing the hoods of motor-cars comprises a rigid angular member 15 upon the one part A to be secured, and on the other part B a device formed of springy material, and comprising an attachment portion 19, an inclined arm 23, and a substantially horizontal arm, these two arms respectively, carrying rollers 25, 22 in overlapping relation as shown in Fig. 3. On bringing the parts A, B, together, the member 15 presses back the roller 25, and takes up the position shown in Fig. 2. The catch is released by raising the arm 20, which can be effected by a thumb-piece 26, or by a cord or a sliding rod, or by pivoted bars operable from both sides of the door. The springy resistance of the roller 25 produces a buffer action upon closing the door, and also assists in starting the opening movement. It may be increased by an additional spring extending across the spring frame. In its application to securing motor-car hoods, Fig. 11, a pair of catches are arranged within a channel bar 39, and are released from engagement with the hooks 15 by a piece 41 connected to a flexible strip 40, which pulls away the arms 20 of the respective devices.
